混凝土抗压强度试验的不确定度分析

Uncertainty Analysis of Concrete Compressive Strength Test

混凝土抗压强度检测在建设工程质量试验中必不可少,文中通过分析C35立方体抗压强度试验结果不确定度的主要影响因素,探究相对不确定度分量的评定,结果表明,影响不确定度大小的因素为试验结果的重复性、测量设备的不确定度、数值修约的不确定度。

Concrete compressive strength testing is an essential test in construction engineering quality testing.This article analyzes the main influencing factors of the uncertainty of the C35 cube compressive strength test results,explores the evaluation of relative and composite relative uncertainty components.The analysis of the test results shows that the factors that affect the size of uncertainty are the repeatability of the test results,the uncertainty of measurement equipment,and the uncertainty of numerical rounding.
